Cup anemometer 3S-WS-PLS-P

IP54heatedwith relay output

Overview
The Plastic Wind Speed Sensor (cup anemometer) 3S-WS-PLS-P measures horizontal wind speed and provides pulse (reed relay) output for direct integration with SCADA, PLC or data loggers. The instrument is designed for outdoor environmental and industrial use with UV-resistant materials and low maintenance needs.

Standards & Note
Compliant with IEC 61724-1:2021. Wind speed data can support module temperature estimation and wind-damage assessments. To monitor gusts (typically up to 3 s), use a sampling period ≤ 5 s and log both average and peak values.

Key Features

• Pulse output for integration: Reed relay pulses for reliable digital counting by controllers and loggers.
• Weather-resistant materials: ASA housing and ABS cups with UV-resistant cable for outdoor use.
• Wide measurement range: From 0.9 to 60 m/s, suitable for calm to high-wind conditions.
• Low maintenance: Simple mechanical design reduces upkeep; optional heated model for icy conditions.
• Compact and lightweight: Easy to mount on pipes or ground fixtures.

How It Works
The rotating cups drive a magnet-activated reed switch; each rotation generates a pulse. Pulse frequency is proportional to wind speed and is counted or measured by the connected system for real-time monitoring or logging.

Why Choose This Sensor

• Accurate measurements: Clear resolution and defined accuracy for operational monitoring and assessments.
• System compatibility: Pulse output integrates with SCADA, PLCs and common data loggers.
• Durability: Materials and design reduce degradation from UV and weather exposure.
• Flexible deployment: Standard and heated options for a range of climates and applications.

Applications

• Wind energy monitoring: Turbine site assessment and performance monitoring.
• Weather stations: Meteorological data collection for forecasting and research.
• Industrial sites: Safety and operational decision support based on wind data.
• Agriculture: Field condition monitoring and spray/operation planning.

Installation & Maintenance
Installation: Mount in an unobstructed location at appropriate height; use pipe or ground mounting as required. Maintenance: Low-maintenance design; periodic cleaning recommended in dusty or polluted environments and inspection after extreme events.

Warranty & Power
Warranty: 2 years covering material and workmanship defects. Power supply: 12–30 V DC.
